We introduced the concept and process of the threshold-based earthquake early warning method. We analyze the universality of this method using the near-field strong-motion data recorded in the Italy Mw 6.2 earthquake on August 24, 2016. Our results indicate that the alert level of each station can be accurately predicted and the extent of the potential damage zone (PDZ) can be rapidly estimated after the first station triggered. The determination of alert level for each station and the estimation of the potential damage zone show reasonably good agreement with the distribution of instrumental intensity of ShakeMap from the U.S. Geological Survey (USGS). The feasibility and validity of this method in Italy Mw 6.2 Earthquake on August 24, 2016 are demonstrated.
